Add Aviation Line Bypass (Aviation)

Resumen

Adjusts route polyline features that overlap point features.

Navigational aids (navaids) are represented on a chart as points that can be symbolized according to their classification. Navaids can represent facilities on the ground, such as a VOR, or imaginary way points as is the case with RNAV. Air Traffic Service (ATS) routes pass over navaids at various points throughout a flight. Navaids can be considered part of the route when they fall directly on the ATS route indicating a change in course, an intermediate step during the flight, or a transition to another route. Because ATS routes can overlap at multiple flight levels on a chart, it can be difficult to tell if a navaid is a part of a route or if the route bypasses the navaid.

When an ATS route bypasses a navaid, the route representing the line is curved slightly where the navaid intersects the route. This does not indicate that the flight path has changed, only that the navaid is not considered part of the ATS route. The following images show the difference between an ATS route that includes a navaid and a route that bypasses a navaid on a navigational chart.

An ATS route with a line bypass is shown.

An ATS route with no line bypass is shown.

Uso

• This tool processes selected polyline features on a map. If no polyline feature is selected, the tool will process all polyline features in the feature class.

• The Input Map parameter must have a set reference scale.

• If you do not provide features for the Bypass Features parameter, the tool will revert all lines with bypass symbology to straight lines.

• Only selected features in the Target Line Features value will be processed by this tool.

• The Radius Scale parameter is only valid if you select Dynamic Radius as the Radius Option parameter value.

• The Radius parameter is only valid if you select Constant Radius as the Radius Option parameter value.

• If you do not provide a value for the Tolerance parameter, all features with overlapping symbology will be processed.

AddAviationLineBypass example 1 (stand-alone script)

The following demonstrates how to use the AddAviationLineBypass function to generate bypasses with a dynamic radius.

# Name: AddAviationBypassLines_Dynamic_Radius_example.py

# Description: ArcGIS geoprocessing tool that adjusts route
# polyline features which overlap point features.


import arcpy

# Check out Aeronautical extension

arcpy.CheckOutExtension("Aeronautical")

# Create a reference to the project file (.aprx) containing your map

aprx = arcpy.mp.ArcGISProject(r"D:\My Project.aprx")
map = aprx.listMaps("My Map")[0]

# Parameters

target_line_features = "ATSRoute"
bypass_features = ["ADHP", "NavaidComponent"]
tolerance = "1 kilometer"
radius_option = "DYNAMIC_RADIUS"
radius_scale = 1.0
radius = ""
merge_option = "MERGE_BYPASS"

# Run AddAviationLineBypass

arcpy.aviation.AddAviationLineBypass(map, target_line_features, bypass_features, tolerance,
                                     radius_option, radius_scale, radius, merge_option)
